Adherence

Mobile phone interventions, specifically text messaging and smartphone applications, are effective tools for promoting weight reduction and increasing physical activity, with the majority of studies showing statistically significant improvements in weight, BMI, or waist circumference.

Use a mobile phone intervention to help with weight loss or physical activity. This can be as simple as sending text messages (SMS) or using a smartphone app to track calories and exercise. The most effective interventions often combine the technology with some form of education or support (like weigh-ins or group meetings). Most users find these tools acceptable and helpful.
